3.3 Calibration
3.3.1 Unit Calibration
After the unit has stabilized (recommended to run overnight); several different systems can be calibrated. In
the calibration mode, the temperature, CO
2
, O
2
(for suppressed O
2
model), and RH reading can all be
calibrated to reference instruments. To determine the exact measured value of the sensors, a comparison
measurement has to be performed every year. If a major deviation is found during this check, calibration of
the sensor is required. This is to ensure continuous and optimal performance of the CO
2
incubator.
A calibrated measuring instrument with higher accuracy (reference instrument) is required.
Place the reference instrument or its measuring probe on the center of work zone. Route the connecting cable
either through the sampling port located on the glass door or the access port located at the rear of work zone.
Close doors and wait until the value displayed in the reference instrument is stabilized. Record the measured
value.
Enter MENU|CALIBRATION and select the responding options. When asked, enter the measured value. Press
SET to confirm.
To reset the sensor to its default calibration, select DEFAULT CALIBRATION. Press SET button to confirm.
